Patent GB-352414-A (GB)
Title: Improvements in or relating to the manufacture of artificial horsehair, strips and ribbons
IPC: D01F2/28
Filed: 1930-04-07
Abstract: Artificial horsehair, strips or ribbons of high flexibility are produced by leading a large number of elementary filaments through a solvent or swelling agent at such speed that the thread is softened at the outer surface only, so that a welding of the filaments takes place through a small thickness of the thread, the filaments within the sheath so formed retaining their individuality.  The process may be combined with the spinning of the threads themselves, the agglomeration being carried out on the threads, which may be twisted or not, after they have been completely freed from solvent.  In the production of strips or ribbons, a bundle of untwisted filaments may be assembled in the desired form prior to agglomeration, or a number of twisted threads may be placed side by side and subjected to the agglomeration process.  The solvent or swelling agent may contain also substances in the state of solution or emulsion, such as gums, resin, copal, colouring matter and the like, or small quantities of the cellulosic product which constitutes the fibre, or other cellulosic product; moreover, the solvent or swelling agent may be varied so as to obtain particular effects such as mat or lustrous effects.  Bronze or aluminium powder, or other pigments may be introduced into the yarn before agglomeration and preferably after a preliminary passage of the yarn through a bath consisting of a suitable gum, resin, varnish or the like.  If desired, these pigments may be fixed to the surface of the horsehair after the agglomeration of the yarn, and at a time when the yarn still contains a small quantity of the solvent or swelling agent.  A pigmented product may also be obtained by emulsifying the pigment with the solvent or swelling agent and, if desired, a binding agent such as copal or resin.  In examples, (1) a cellulose acetate yarn comprising 72 filaments is passed through a bath of acetone, which is traversed in one-hundredth of a second, the yarn then passes on to a wiping device.  (2) 10 threads of cellulose acetate each comprising 48 filaments are united to form a sheet of parallel threads and passed through a bath of acetone, the duration of the passage through the acetone being less than one-hundredth of a second; the sheet of threads is then passed between two indiarubber lined rollers. Specifications 326,462 and 328,312, [both in Class 2 (ii), Cellulose &c.], are referred to.

Abstract: 1,142,492. Non-circular glass filaments, manufacture. DEBELL & RICHARDSON Inc. 14 March, 1966 [16 April, 1965], No. 11036/66. Heading C1M. [Also in Division F2] To make glass resin composite structures, a non-circular glass preform is advanced through a chamber heated to a temperature between the softening and flow temperatures of the glass and is attenuated to give a glass filament of the same cross-section as the preform which is wound in overlapping relation on a mandrel and a thermosetting resin is then applied. The filament has a width to thickness ratio of between 10-50 to 1 and a thickness in the range of 0À0002 to 0À004 of an inch. A glass preform 8 is fed by mechanism 11 through a furnace 12 containing electrical elements 14 parallel to the preform and the glass is attenuated by a draining mechanism 18 to form a filament 10. Resin is applied by an applicator 17 and a guide 24 is slowly reciprocated parallel to a take-up drum 22 to lay the filaments in contiguous edge to edge relation. The furnace 12 is provided with a thermocouple to control accurately the temperature therein and a graphite disc 30 seals the upper part, the opening in the disc 30 matching the preform. The lower opening 16 is provided with coolers 32 to rapidly cool the filament 10. The filaments 4 (Fig. 3) are wound in overlapping arrangement to give a longer flow path I through the wall thickness t than with circular filaments in tubular structures. A preform for corrugated filaments, Fig. 10, consists of a glass plate 40 with rods 44 cemented thereto by a cement which turns off during attenuation. Hollow rectangular filaments may be attenuated from four glass plates cemented together.

Title: Improvements in and relating to multi-rotor helicopters
IPC: B64C1/00
Filed: 1948-04-22
Abstract: 646,867. Multi-rotor helicopters. CIERVA AUTOGIRO CO., Ltd., PULLIN, C. G., SHAPIRO, J. S., and BOLAS, H. April 22, 1948, No. 11089. [Class 4] In a multi-rotor helicopter having at least one pair of sideby-side lifting rotors, control in roll is obtained by transverse differential collective pitch control, and control in yaw by differential inclination in the pitching plane of the lift vectors of the side-by-side rotors and by a rudder or rudders, both yaw control members being operated by the same pilot's control member. Figs. 4 and 5 show a control system for a helicopter with three lifting rotors, as described in Specification 591,982, in which a spider with three arms 47, 48, 49 is mounted for universal tilting and vertical movement by operation of an attitude control lever 38 and a collective pitch control lever 40, respectively, the ends of the spider arms being connected by links 50, 51, 52 to the collective pitch control mechanisms of the respective rotors. Transverse movement of the lever 38 is transmitted to the spider by links 62, 63, 65, 56 to move the links 51, 52 equally in opposite directions, resulting in differential variation of the collective pitches of the side-byside rotors. Fore-and-aft movement of the lever tilts the spider about a transverse axis, through links 61, 53, 55. The rudder pedals 39 are connected by links 86, 87, 82 to a lever 75 whose ends are connected by links 78, 79 to the cyclic pitch control systems of the rear side-byside rotors, and also by a link 92 to pulleys 94, 95 connected by chains 98, 99 to sprockets 102, 103 actuating rudders 36, 37 through links 106, 107. By this arrangement the control exerted by the rudders becomes progressively more powerful as the forward speed increases, and the effect of the rotors is correspondingly reduced, this minimizing the rolling couple resulting from the differential inclination of the rotor lift vectors. In the case of a helicopter with four rotors arranged in diamond plan formation, the three-armed collective pitch control spider is replaced by one with four arms, Fig. 8 (not shown), and the links 78, 79 are connected to the cyclic pitch control mechanisms of the side-by-side rotors, there being no cyclic pitch control of the front and rear rotors. The three-armed spider shown in Fig. 4 may be replaced by a T-bar which may be constructed and power-operated as described in Specification 646,864. All the rotors are preferably driven in the same direction. Specifications 644,524 and 646,866 also are referred to.

Title: Improvements in and relating to shadow meters employed as tuning indicators in wireless receivers or the like
IPC: H03J1/04

Abstract: 434,932. Wireless receiving-apparatus. PLESSEY CO., Ltd., Vicarage Lane, Ilford, Essex.-(Mallory & Co., Inc., P. R. ; 3029, East Washington Street, Indianapolis, Indiana, U.S.A.) April 11, 1935, No. 11295. [Class 40 (v)] [See also Group XXXVI] A shadow meter for giving visual indication when a receiver is exactly in tune comprises a casing 11 of non-magnetic but electrically conductive material, and a light source comprising a lamp 22, the light from which passes through a slit 44 in the casing to a translucent screen 15, casting thereon the shadow of a vane 42. The vane 42 is carried by an armature 36 mounted to swing freely about a horizontal axis thereby oscillating the vane in a vertical plane. An electromagnet 47 is housed in a metal case 56 secured by tongues to the casing 11, the cone 48 of the electromagnet being mounted on the case 11 by a screw 53 and bracket 40 which also provides one bearing for the armature 36. The limb 51 of the electromagnet projects into the casing 11 at 55, Fig. 3, the central portion 54 being slotted away. A permanent horseshoe magnet 33 is mounted on the outside of the case 11 with its flux at right angles to the field of the electromagnet so that the two fields oppose in their effect on the armature 36. The armature is normally held horizontal by the permanent magnet but when the electromagnet is excited by the anode current of the detector valve, the armature is swung against the stop 59. The vane thus casts a wide shadow on the screen 15 until the fall in anode current when the receiver is exactly tuned causes the permanent magnet to regain control of the armature, the vane again assumes a vertical position and the shadow is reduced to a thin line. Oscillation of the vane is prevented by eddy current damping due in part to the metal casing 11.
